The monitoring group said it was the highest number of dead among Syrian forces in a single such "Israeli attack".

The attacks on Friday targeted several areas in Aleppo’s countryside, Syria’s Ministry of Defence said. It did not provide casualty figures, only saying a number of civilians and military personnel were killed and property was damaged after Israel and unnamed armed groups carried out the strikes, according to Syria’s state news agency SANA.
